Problems solved by technology

However, the problem of manual assembly is: the installation of the shaft sleeve is very difficult. During the assembly process, it is necessary to manually hold the shaft sleeve for multiple adjustments. The stability of the hand-held installation is very poor. The shaft sleeve is stuck during the assembly process, resulting in damage to the axle surface and loss of quality
The manual operation cycle of a single set of bogie wheels is 1 hour, and the work efficiency is low

Abstract

The invention provides an assembly device for a shaft sleeve and a vehicle shaft of a bogie wheel pair. The assembly device comprises a bogie supporting base, and the base is fixedly provided with vehicle shaft fixing devices limiting the vehicle shaft position to be immovable and shaft sleeve fixing devices which support the shaft sleeve and are capable of making the shaft sleeve rotate to be assembled with the vehicle shaft correspondingly. By means of the assembly device for the shaft sleeve and the vehicle shaft of the bogie wheel pair, holding the shaft sleeve manually is not needed, andthe installation quality and the assembly quality of the shaft sleeve and the vehicle shaft of the bogie wheel pair can be improved.

Description

technical field [0001] The invention belongs to the technical field of rail vehicles, in particular to a bogie wheel set axle sleeve and axle assembly device in the rail vehicle production process. Background technique [0002] The bogie wheel set is a key and important part of a high-speed train. The assembly accuracy of its bushing and axle is very high, and the assembly gap is extremely narrow, generally controlled at about 0.1mm. When assembling the shaft sleeve and the axle, it is restricted by factors such as single-piece manufacturing tolerance, assembly matching accuracy, and poor adaptability after interference matching. For many years, manual assembly has been carried out relying on the assembly experience of the operator. The main reason is that it relies on manual The flexible adjustment avoids poor matching, interference assembly and other quality problems that easily cause surface damage of parts during assembly. However, the problem of manual assembly is: the...
